vTo all whom it may concern Be it known that I, JOSEPH BANDIERI, a citizen of the United States, residing at Cincinnati, in the countyof Hamilton and State of Ohio, have invented a certain new and useful Improvement in Surgical Instruments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

lThis invention relates to surgical instruments and especially to that type of surgical instrument known as a syringe, and has for its particular object the .provision of a device of this character suited for either rectal or vaginal use and adapted to thoroughly cleanse and eiciently disinfect that part of the body with which it is used, whereby any germs, bacteria, or other living organisms will be killed and destroyed, and any fetid or decomposing matter will be rendered innocuous. This result is attained by imparting to the fiuid with which the parts are washed a sterilizing quality, and the object `oil! this invention 1s to produce a device whereby this quality is imparted by the operation of the instrument itself and without the use of noxious and dangerous chemicals or drugs. n I

More limitedly2 the object of the inven tion is the provision of a device of this electrolyzed at the very point of use and thus broken up into substances which have a well known sterilizing edect and without any injurious action upon the tissues of the human body itself.

@ther objects of the invention concern the construction and arrangement of parts' whereby a simple, reliable, edicient, and cleanly device is produced, and one in which the danger of shocking or burning the patient is entirelyavoided.

Generally spea ng my invention may be defined as consisting of the combination of elements recited in the claims hereto annexed and illustrated in the drawings accompanying and forming a part here/of, wherein- Figure 1 represents a side elevational view of the complete device; Fig. 2, a top plan View of the same; Fig. 3, a central longitudinal cross sectional view parallel to the plane of the paper; Fig. 4, a view similar to Fig. 3 taken at right angles thereto; Fig. 5, a transverse cross sectional view taken along the broken line 5-5 of Fig. 4 and looking in the direction of the arrows; Fig. 'is a diagrammatic view illustrating the preferred method of supporting the electrode wires so as to avoid short-circuiting while keeping them at substantially equal distances from each other; and Fig.' 7 is a central cross sectional view, throu h a modified form of casing, the electric eatures being omitted so as to provide for the free washing of the parts to be treated.

Describing the parts by reference characters, my evice comprises a hard rubber cannula 1 of truste-conical form, having the smaller end rounded as at 2 and having the larger end formed with a laterally projecting threaded la'nge. The sides and end of this cannula are formed with perforations 4 the size whereof preferably decreases from the base to the apex thereof as illustrated in Fig. 1. Secured to the larger end of the cannula; as by means of screw-threads 5, meshing with those on the dange 3, is a hard rubber convex disk 6, which is preferably oval in outline as illust-rated in Fig. 2. The sideA of this disk opposite to the cannula one may if desired be made slightly concave as illustrated at- 7. At the base of said cannula is a hard rubber block 8 preferably cyy lindrical in general outline and having a for wardly extending axial plug 9 adapted to enter the open larger end of the cannula and be retained therein by friction. This plug is pierced by an axial recess 10 which merges with a smaller axial recess 11, and in this latter recess is secured in any convenient manner a. tube 12, preferably also o rubber and projecting substantially to the smaller end of the cannula as shown in Figs. 3 and d. The recess 10 communicates at its inner end with a laterally opening recess 13 in which is secured a nipple 14 adapted for the reception of a Hexible pipe 15 through which suitable liquid may be conveyed to the device. The vrecess 11 also communicates with a laterally opening recess 15, preferably opposite the recess 13, and in this latter recess is secured a nipple 16 which is preferably provided with a stop cock 17. To this electrical suppl Suitable lead wires 23 lead inwardly fiom these bindingposts or connectors through the block 8 and plug 9, where they are connected to Suitable metallic electrodes, the preferred construction and 'ported in, suitable apertures or notches formed in these disks are platinum wires 26 -which comprise the electrodes. Referring particularly to Fig. 6 wherein the preferred arrangement of wires is shown, it will be seen that the wire from the positive terminal is rst led downwardly past the edges of the y. disk 25, as at 26a, until the lowermost disk is reached, thence across this disk at one side of its center to the opposite edgel thereof, which it cutspreferably at a point 120 degrees from the first intersection, thence Y upwardly past the edges of the disks to the uppermost disk to a point 120 degrees removed from the starting point, thence across said disk to a point 120degrees removed from the opposite side of said starting point, and lastly downwardly past the edges of the disks to an intersection with the lower disky at a point 120 degrees removed from both the former intersections. The other electrode is preferably led downwardly from the negative terminal at 26" past the edges of the disks at a point opposite the first portion of the positive electrode, thence across the lower disk as inthe first case, but keeping everywhere parallel t0 the positive electrode,

.thence upwardly by the edges of the disks across the upperdisk, still parallel to the rst electrode, thence downwardly and ending at the smallest disk as before. rangement permits the use of a large quantity of wire, with the smallest possible danger of the same being short-circuited, and

with a substantially uniform resistance between all parts of the electrodes from the v fact that they, are everywhere substantially equidistant. The wire of which these electrodes are formed is preferabl bent into a sinuous or serrate form as illustrated in Figs. 3 and 4, so as to increase its length and consequently augment the area of the electrode. A greater number of turns of the electrodes can also be employed if desired by making the intersections thereof with the disks nearer each other while maintaining the same general arrangement.

In Fig. 7 I have illustrated a modied base block 8, wherein .the electrical features are entirely omitted, the central tube 12 being led directly through the base of'this block as illustrated at 30, and there formed for the reception of afiexible tube. The inlet nipple 14a is secured in the side of the base block as before. This base block is preferthe This arcleansing fluid. The block 8a is then re. v

placed by the block 8, the liquid again supplied to the parts, andthe electrical current turned on. The effect of the latter will be to electrolyze the liquid so as to break it up into its elements,v which have a well known therapeutic and sterilizing action, roducts of such decomposition being carried forward by the iiow of incoming fluid into intimate contact with the portions being treated. Under ordinary conditions water'may be employed with good results, the natural impurities in the water, taken with the substances dissolved vthereby during its use, serving to impart suiiicient conductivity for the practical operation of the device. The yproducts of the decomposition in this case will be hydrogen and oxygen, both of which are in a nascent state and hence possess unusual activity, together with a small quantity of ozone whose benelicial nature is well understood. Incase greater efcacybe desired a slightly saline solution maybe used which will be broken up by the electric current into chlorin and caustic soda, both of which will be dissolved in the liquid and carried onward to the portions treated, and, though in extremely dilute solution, will exert marked beneficial properties. If desired a considerable quantity of liquid can be introduced through the device at one time, and retained therein by the disk 6, the stop cock 17 being closed. The current being turned on the strength of the solution can be'increased to any desired ex-v tent by the accumulation of the products of dissociation; or the rate of flow can be regulated so that the incoming fluid will sweep slowly, past the electr0des,bearing with it the cleansing and'sterilizing agents. It will also be seen that the disks 25 serve as batl'le plates or deflectors to divert the inflowing liquid outwardly through the perforations in the cannula and into contact with the parts undergoing treatment. This, taken inl connection with -the location of the electrodes` closely adjacent to the cannula wall, causes the products of decomposition of the liquid to be projected Lupo-n the treated surfaces While still in nascent condition, whereby their efliciency and potency are greatly increased. The spent liquid returns to the outfiow tiibe 12 by again entering the end ofr the cannula, the direction of flow at every point being well illustrated by the arrows in Fig. 3. Thus the disks 25, in addition to supporting the electrodes, also serve to* imamamos pedo the direct passage of electrolyzed liquid from the annular chamber between the tube and cannula wall to the interior of said tube, and thus fail to come into contact with the alilicted parts. Even if the disks should be omitted and some other form of electrode support employed the converging character of the cannula walls would still serve to induce some outflow of the liquid, although, of course,l in less degree.

It will therefore be seen that l have produced a device capable of cleansing and ste-riliaing with great thoroughness the parts of the body-with which it is used. It will also be appreciated that while l have necessarily described my invention in detail, thesedetails may be departed from considerably Without impairing the eHicacy of the device or avoiding thelscope of the claims hereto annexed. 4
